HENRY WALSH, OF OLDHAM, ENGLAND.

MECHANISM FOR STRIPPING TEETH 0F REVOLVING FLATS OF CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent N 0. 662,581, datedNovember 2'7, 1900.

Application filed September 1, 1899. serial No. 729,175. (No model.)

To aZZ whom it may concern;

Be it known that I, HENRY WALSH, a subject of the Queen of GreatBritain, residing at Oldham, in the county of Lancaster, England, haveinvented new and useful Improvements in Mechanism for Stripping theTeeth of Revolving Cards in Oarding-Engines, (for which I have madeapplication for patent in Great Britain, No. 6,740, bearing date March29, 1899,) of which the following is a specification.

Hitherto in carding-engines with revolving flats the waste fibers orstrips have been removed from the card-teeth of the flats by a comb orcard having an up-and-down or oscillating movement imparted andreciprocating in the same path over the surface of the card-teeth. Inpractice it has been found that the said reciprocatory motion oftendamages the teeth of the comb and flats by coming into contact with eachother, which contact takes place owing to the flats being pressed fromthe periphery of their blocks or disks by particles of dirt and fluffentering between the ends of the flats and the blocks or disks or owingto the flats hanging loosely from the latter through the elongation ofthe chain-links of the flats, and as the delicate nature of thecard-teeth of the flats does not permit of them being bent backward andforward through the said defect the card-teeth break frequently.

The object of my invention is to provide means whereby the said defectsare entirely obviated and the cards are combed or stripped morenaturally and effectively than hereto fore has been the casenamely, inthe direction of the angle of the card-teeth on the flats and therebyrender it very easy to draw the waste fibers from the same. I attainthese objects by the mechanism illustrated in the accompanying twosheets of drawings, in which- Figure 1 is an end View; Fig. 2, asectional plan; Fig. 1 a diagram of my improved cardstripping motion.Fig. 3 is a sectional end view, and Fig. 4 a sectional plan, of myimproved card-stripping motion adapted for use of existing combs.

Similar letters refer to similar parts throughout the several views.

a is the bracket, bolted to the outer side of each bend carrying thedisks 1), which support the flats c. To each of the said brackets issecured a bearing formed in two parts cl 2, the outer part e of which isrendered adj ustable upon the inner part at. In each of the said outerparts is mounted a disk or cylindrical body f, one of which is formedwith a stud g, having secured thereto a rope pulley h, by which the saiddisks or cylindrical bodies are jointly rotated from any suitable movingpart of the carding-engine. To the disks or cylindrical bodies f Isecure eccentrically a shaft t', which connects the same together so asto form a double crank, and upon the latter I place a tube is, to whichis attached the comb Z, by which the teeth of the card-flats o arestripped, the said disks or cylindrical bodies and shafts actuating thesaid comb in crank fashion. Upon the said tube I secure at one end aring m, having an arm n, the free end of which is received by the socket0, mounted in the bearing a, so that the otherwise concentric path ofthe teeth of the comb l is converted into an eccentric or irregular oneor path resembling an ellipse. (See more particularly Fig. 1 By thesetscrew 19 in the ring m the comb Z is rendered adjustable therein, sothat the teeth of the comb can be set to move at any required anglerelative to the card-teeth.

According to a modification (see Figs. 3 and 4) the said crank motionand irregular or path of the comb resembling an ellipse may be obtainedby employing in each of the bearings e an eccentric f, and upon the samethe tube 7t, which carries the comb Z and the ring m n, as in the formerinstance.

According to another modification instead of employing the combl upon atube, as in the former instance, I may dispense with such tube entirely,as shown in Figs. 3 and 4, and employ loosely upon the shaft t', whichin the previous instance carries the said tube, two arms q, to the freeends of which I secure the bar 71, carrying the comb as hitherto in use,while the ring m n I secure to the boss of one of the arms q.

What I claim as my invention, and desire to secure by Letters Patent,is-- In mechanism for stripping the teeth of revolving carding-engines,in combination two disks f, f, connected together eccentrically by aremovable shaft i forming a crank-neck, said crank-disks, jointly in thesaid bearings,
